Avira> their novel ideologies.
We need to admit that new circumstances usually require new approaches, not necessarily ideologies. And people often do not know in advance what will work.
I re-re recenty in a row Chofetz Chaim and r Soloveichik letters. Comparison is a little unfair – former are from 1920-30s, latter – 40-50s, but Chofetz Chaim letters are a cry in the wilderness when things are getting worse every year in Poland, he repeats – dont send kids to anti-religious schools, have at least one kosher cheder in town … he is not even mentioning Bais Yaakov that he endorsed, while r Soloveichik proposes a very specific training system for rabbis, streamlined to mass-produce rabbis that could lead American Orthodox communities. We can argue whether his plan was implemented and to what success, but it was a well defined plan _novel _ to address a real problem.
